Solution to test 1 , its
distribution ,
the distribution of each question ,
and the correlations between them.
UPDATE: You can find all of your recorded scores in the complete spreadsheet
here, and the distribution
of the various components of the final score (i.e., hw, qz, test, etc.). The
distribution of the final score (last histogram) determines the final grade
in the course. IT IS YOUR RESPONSIBILITY TO ASSURE THAT THESE GRADES ARE
CONSISTENT WITH YOUR OWN RECORDS. LET ME KNOW IF THEY ARE NOT. A "-99" means
that I don't have a score for that item; these will be converted to
zero unless they are corrected. Here is more explanation. Solution to test 2 , its
distribution ,
the distribution of each question ,
and the correlations between them.

I STRONGLY recommend that you download
a free version of R for your own machine, because we may not have enough
desktops for everyone in the lab! If you do install R, bring your machine to
